Influence of microleakage, surface roughness and biofilm control on secondary caries formation around composite resin restorations: an in situ evaluation

SUMMARY Objectives: The aim of this clinical study was to evaluate the clinical performance of Class II restorations of a high-viscosity glass ionomer material, of a bulk-fill composite resin, and of a microhybrid composite resin. Methods and Materials: One hundred nine Class II restorations were performed in 54 patients using three different restorative materials: Charisma Smart Composite (CSC; a conventional composite resin), Filtek Bulk Fill Posterior Restorative (FBF; a high-viscosity bulk-fill composite), and Equia Forte Fil (EF; a high-viscosity glass ionomer). Single Bond Universal adhesive (3M ESPE, Neuss, Germany) was used for both conventional and bulk-fill composite resin restorations. The restorations were evaluated using modified US Public Health Service criteria in terms of retention, color match, marginal discoloration, anatomic form, contact point, marginal adaptation, secondary caries, postoperative sensitivity, and surface texture. The data were analyzed using the chi-square, Fisher, and McNemar tests. Results: Eighty-four restorations were evaluated at two-year recalls. There were clinically acceptable changes in composite resin restorations (FBF and CSC). In addition, no statistically significant difference was observed between the clinical performances of these materials in terms of all criteria (p>0.05). However, there was a statistically significant difference between the EF group and the FBF and CSC groups in all parameters except for marginal discoloration, secondary caries, and postoperative sensitivity (p<0.05). Conclusions: The tested bulk-fill and conventional composite resins showed acceptable clinical performance in Class II cavities. However, if EF is to be used for Class II restoration, its use should be carefully considered.

The aim of this study was to analyze the features of secondary caries and their relationship with the presence of restorations marginal defects as gap, negative ledge (NL, lack of restorative material) and positive ledge (PL, overhang). Eighty proximal surfaces of Class II resin restorations were photographed and analyzed using a stereomicroscope (X40). It was recorded the presence of external secondary caries, gap, NL, PL and after the restorations removal, the presence of internal lesion. All the exams were done in 10 well-defined points. The reproducibility (Kappa Index) of the exams of external caries, presence of gaps, restorations marginal defects and internal caries were, respectively: 0.88 e 0.94; 0.80 e 0.87; 0.83 e 0.90 e 0.82 e 0.94. As reprodutibilidades (Kappa) dos exames de cárie externa, EDR, presença de degraus e cárie interna no início e depois da análise de 50% da amostra foram, respectivamente: 0,88 e 0,94; 0,80 e 0,87; 0,83 e 0,90 e 0,82 e 0,94. The prevalence of secondary caries (p < 0.05) and gap (p < 0.01) were associated with gingival margin. The restorations marginal defects (NL and PL) were not associated with any specific location (buccal, lingual or gingival) (p= 0.073). It was observed a relationship between these defects with secondary caries prevalence (gap: p= 0.004; NL and PL: p= 0.017). This association could be explained by the biofilm accumulation usually observed in the interface tooth surface/ restoration marginal defects. The presence of internal lesion was associated with external lesion (p< 0.001). Although, in 141 points was observed internal lesion without the presence of external lesion. The majority of these lesions showed internal enamel involvement. Only 8% had demineralization restricted to dentine, which could suggest residual caries. The results of this study showed that secondary caries lesion frequently began externally on the interface tooth/restoration, where diagnose, control and arrestment of the lesions is possible.

AbstractThe choice of the best finishing/polishing methods for composite resin restorations is critical to the choice of excellence results related to longer clinical longevity. The objective of the study was to evaluate the influence of finishing and polishing systems on the surface roughness of a Nanoparticulate and Bulk-fill resin. For the research, 40 sample disks were prepared for each composite: single-increment (BF) (Bulk Fill 3M), both 2 mm thick and 10 mm in diameter (FZ) (Filtek Z350, 3M). The specimens were randomly divided into 4 groups with 10 samples each, according to the different materials to which they were subjected to the finishing and polishing protocols: control [C]- diamond tip (FG 4137F, FAVA); [EN] polishing discs (Enhance, Dentsply); [SL] Abrasive discs (Sof-Lex Pop-on, 3M) and [PD] felt disc + Polishing paste (Diamond Excel, FGM). A surface roughness (Ra) was verified with a roughness meter in three different data volumes and calculated as arithmetic means. Data were statistically treated by one way ANOVA followed by test t and student t test. Regardless of the data tested, evidence of the systemic controlling against different systems for polishing control with control (p <0.05). PD presented statistically greater roughness to the EN and SL (p <0.001), these in turn obtained similar performance and presented the lowest values of roughness for both composites (p> 0.05). The different finishing / polishing methods influenced the surface roughness of both composites, observing for Sof-lex and Enhance lower Ra values.Keywords: Nanoparticles. Dental Polishing.

O objetivo desse estudo foi avaliar a influência dos sistemas de acabamento e polimento na rugosidade de superfície das resinas nanoparticuladas convencional e bulk-fill. Para a pesquisa foram confeccionados 40 discos de amostra para cada compósito: Convencional [FZ] (Filtek Z350, 3M) e de incremento único [BF] (Filtek Bulk Fill, 3M), ambas com 2 mm de espessura e 10 mm de diâmetro. Foram divididos aleatoriamente em 4 grupos com 10 amostras cada, de acordo com os diferentes protocolos que receberam, sendo: controle (C) ponta diamantada (FG 4137F, FAVA); (EN) discos de silicone (Enhance, Dentsply); (SL) discos abrasivos (Sof-Lex Pop-on, 3M); (PD) Feltro + Pasta diamantada (Diamond Excel, FGM). A rugosidade de superfície (Ra) foi verificada com um rugosímetro em três leituras de diferentes direções e calculadas as médias aritméticas. Os dados foram tratados estatisticamente pelos testes ANOVA 1 fator seguido pelo teste t e t de student (p<0,05). Independente da resina testada, evidenciou-se diminuição da rugosidade pelos diferentes sistemas de polimento frente ao grupo controle (p<0,05). PD apresentou rugosidade estatisticamente maior à EN e SL (p<0,001), estes últimos que por sua vez obtiveram desempenho semelhante e apresentaram os menores valores de rugosidade para ambos os compósitos (p>0,05). Os diferentes métodos de acabamento/polimento influenciaram na rugosidade de superfície dos dois compósitos testados, observando para Sof-lex e Enhance menores valores de Ra.

ABSTRACT Aim The purpose of this study was to determine the effect of different solutions cola soft drink (CSD) and coffee on roughness and microleakage of composite resin restorations. Materials and methods Sixty bovine incisors were prepared and restored using Filtek Z350 XT (3M/ESPE) nanoparticulate resin. The samples were divided into three groups (n = 20): A (control)-Immersion in artificial saliva (14 days); B: Immersion in coffee (14 days), for 15 minutes (3x/day) and C: Immersion in CSD for 14 days (3x/day). Then the samples were analyzed for microleakage (dye penetration) and surface roughness (atomic force microscope). The one-way analysis of variance (ANOVA) was applied to assess the surface roughness and microleakage. The Tukey's test was set at 0.05. Results Group A (roughness-GAR) presented significantly the lowest average surface roughness. Group C (microleakage- GCM) showed significantly the highest average microleakage. Conclusion It was concluded that CSD and coffee change the surface roughness and increase the microleakage of restorations. Clinical significance Nowadays there is a high consumption of artificially sweetened soft drinks, sports drinks, high-energy beverages and coffee products by people that cause problems in composite resin restorations.

AbstractFactors such as aesthetics and adhesion to dental substrates have consolidated composite resin as a restorative material for posterior teeth, however, the performance is unsatisfactory regarding the longevity of these restorations. The purpose of this retrospective cross-sectional observational study was to evaluate the reasons that resulted in failure of class I and II Black composite resin restorations, performed by undergraduate dental students at the State University of Londrina. The patients were selected from the research of the medical charts filed at the University Dental Clinic's Screening Department. The restorations were evaluated by two calibrated dentists. The data collected were tabulated and analyzed using descriptive statistics, function Cont IF. Of the 261 class I and II restorations evaluated, 150 (57.5%) were in need of replacement. The main causes of failure of class I and II restorations were secondary caries (46.7%), followed by fracture (19.3%) and loss of marginal adaptation (16.7%). Of all the restorations made by the 3rd grade students, 68.4% failed, 57.4% performed by the 4th grade students and 53.9% of the 5th grade students. Based on the results, it is concluded that the main reasons for restorations failure were secondary caries, fracture and loss of marginal adaptation according to the evaluation criteria. Restorations performed by students in the 3rd grade showed a higher percentage of failures compared to those performed by students in the 4th and 5th grades. Keywords: Permanent Dental Restoration.

Resumo Fatores como estética e adesão aos substratos dentários têm consolidado a resina composta como material restaurador para dentes posteriores, entretanto, o desempenho mostra-se insatisfatório em relação a longevidade destas restaurações. O objetivo desse estudo observacional transversal retrospectivo foi avaliar as razões que resultaram em falhas das restaurações de resina composta de classe I e II de Black, realizadas por alunos de graduação em Odontologia da Universidade Estadual de Londrina. Os pacientes foram selecionados a partir da pesquisa dos prontuários arquivados no Setor de Triagem da Clínica Odontológica Universitária. As restaurações foram avaliadas por dois avaliadores, cirurgiões-dentistas, calibrados. Os dados coletados foram tabulados e analisados por meio de estatística descritiva, função Cont SE. Das 261 restaurações classes I e II avaliadas, 150 (57,5%) apresentavam-se com necessidade de substituição. As principais causas de falhas das restaurações classes I e II foram: cárie secundária (46,7%), seguido de fratura (19,3%) e perda de integridade marginal (16,7%). Dentre as restaurações realizadas por alunos da 3ª série e avaliadas, 68,4% falharam, da 4ª série 57,4% e da 5ª série 53,9%. Com base nos resultados, conclui-se que as principais razões de falha das restaurações foram cárie secundária, fratura e perda de integridade marginal, de acordo com os critérios de avaliação. As restaurações realizadas por alunos da 3ª série apresentaram maior percentual de falhas, comparadas as realizadas pelos alunos da 4ª e 5ª séries. Palavras-chave: Restauração Dentária Permanente.
